Ovarian steroid cell tumors (OSCT) are rare sex cord stromal tumors of the ovary and comprise <0.1% of all ovarian tumors. We herein report a case of an OSCT in a 9 year old girl patient who presented with central puberty preocious unresponsive to gonadotrophine relasing hormon analog (GnRH) therapy. A 9 year old girl presented with breast development noticed 4 months ago and menarche 3 months ago. Her height was 141,5 cm (+1,3 SDS), body weight was 35.4 kg (+0.9 SDS) and...

Thyroid Function and Autoimmunity and Their Relation to Weight Status in Healthy Children and Adolescents

Garcia-Garcia Emilio , Galera-Martinez Rafael , Garcia-Escobar Iciar , Oliva-Perez Patricia , Gomez-Llorente Jose L. , Momblan Jeronimo , Vazquez-Lopez Maria A. , Perales Antonio Bonillo

Background: The interrelationships between body weight and thyroid status are complex. Serum TSH is typically increased in obese compared with lean individuals. Several mechanisms leading to hyperthyrotropinemia have been hypothesized.Objective and hypotheses: To compare thyroid function and autoimmunity in normal, overweight and obese healthy children and adolescents in our population. To analyse any metabolic risk factor related to hyperthyrotropinemia...

Introduction: Neonatal diabetes mellitus (NDM) is a rare monogenic disease associated with genetic defects in pancreatic beta cell number and/or function. It can be divided into two forms: transient neonatal diabetes mellitus (TNDM) and permanent neonatal diabetes mellitus (PNDM). TNDM is usually diagnosed within the first month after birth and usually regresses before the age of one year, but may reappear during adolescence. In contrast, PNDM is a lifelong di...

PTEN Hamartoma Tumor Syndrome (Overlap of Cowden syndrome and the Bannayan-Riley-Ruvalcaba Syndrome): Case Report

Manyas Hayrullah , Çatli Gönül , Eroglu Filibeli Berna , Ayranci Ilkay , Özdemir Taha Resid , Dündar Bumin Nuri

Introduction: PTEN Hamartoma Tumor Syndrome (PHTS) is a rare disease with dominant inheritance characterized by benign (hamartoma) and malignant tumors (breast, endometrium, thyroid). Mutations in the tumor suppressor gene phosphatase and tensin homologue (PTEN) gene are responsible for the etiology.Objective: In this case report, we present an 11-year-old male who was being monitored due to follicular thyroid cancer, an...

MKRN3 Gene Mutation in a Case of Familial Central Precocious Puberty

Eroğlu Filibeli Berna , Ayranci İlkay , Manyas Hayrullah , Kirbiyik Özgür , Dündar Bumin , Çatli Gönül

Introduction: Gain-of-function mutations in KISS1 and KISS1R genes and loss-of-function mutations in the gene encoding the makorin RING-finger protein 3 (MKRN3) expressed only in the paternal allele are the most common genetic reasons of familial central precocious puberty (CPP).Aim: We report a case of familial CPP and a pathogen variant in the MKRN3 gene.<stron...

Aim: Arthrogryposis Multiplex Congenita type II is an autosomal dominant disease, characterized by multiple congenital contractures in the limbs without a primary neurological deficit. The most frequently observed clinical features are triangular face, palpebral fissures facing downwards, clarity in nasolabial folds, small mouth, high palate, adherent ear lobes, short stature, camptodactyly, ulnar deviations in the fingers, vertical talus and/or talipes equinovarus.<p clas...

Triac Treatment Response to Thyroid Hormone Resistantance

Cinaz Peyami , Uğurlu Aylin Kılınc , Doğer Esra , Akbaş Emine Demet , Bideci Aysun , Camurdan Orhun

Aim: Resistance to thyroid hormone (RTH) is a disease characterized by decreased sensitivity to thyroid hormone in the peripheral tissues such as cell membrane, metabolism, or nuclear receptor. In THRB gene mutation induced RTH, the effect of T3 on TRβ mutant receptors in the liver and the pituitary decreased, on TRα receptors located in the brain and heart increased. Triac’s activity is similar to T3.Case: A 1-month-old girl patient was a...

Non-invasive techniques to detect early signs and determinants of diabetic peripheral neuropathy in children with type 1 diabetes.

Eilers Miriam , Fellmann Metsnanat , Wurster Janina , Meier Sandro , Lütschg Jürg , Oberhauser Sarah , Heldt Katrin , Philip Broser , l'Allemand Dagmar

Background: There is an urgent need for better detection of early subclinical manifestations of microvascular complications of diabetes such as peripheral neuropathy (DPN), which already occur in children. The gold standard for the diagnosis of DPN is the measurement of nerve conduction velocity (NCV), which, however, can only detect changes in the large myelinated fibres. At the initial stage of DPN, small, unmyelinated nerve fibres are damaged. High-resoluti...

Pubertal virilization in individuals with partial gonadal dysgenesis attributable to DHH mutation: a case report

Günay Aylin , Kurt İlknur , Ayaz Burcu , Karagözlü Akgül Ahsen , Ersoy Ayşenur , Bilge Geçkinli Bilgen , Yavaş Abalı Zehra , Nuri Özbek Mehmet , Güran Tülay

Introduction: Desert hedgehog (DHH) is mainly involved in testicular development and peripheral nerve sheath formation. DHH protein is produced by Sertoli cells and promotes Leydig cell development. It regulates androgen synthesis through Sertoli-Leydig cell interaction and is also involved in sex differentiation. Biallelic DHH (MIM*605423) variants are an extremely rare cause of 46,XY gonadal dysgenesis (GD). Patients may present with abnormal genita...

Introduction: Peripheral precocious puberty is a non-gonadotropin-dependent early pubertal development. Exogenous intake of sex steroids, gonadal or adrenal pathologies, ectopic hCG-secreting lesions play a role in the etiology. Adrenal tumors is a rare cause of heterosexual precocious puberty.Case: An eight-year-old female patient was admitted with the complaints of genital hair growth and breast enlargement. The patien...
